how to downgrade pricing tier from Premium (+ Role-based access controls) (Click to change) to Starndard

@RSingh - Thanks for the question and using MS Q&A platform.

This is a known limitation with Azure Databricks workspace with Premium (+ Role-based access controls).

Error message: Error: InvalidSkuForDefaultCatalog, Default Catalog selection is only available for Premium workspaces.

Cause: Databricks started to enable new premium workspaces for Unity Catalog automatically and after enabling a workspace for Unity Catalog, it cannot be reversed. If it has Unity Catalogenabled and unfortunately cannot be downgraded. This seems to be a feature limitation and a possible workaround would be to migrate to a new workspace in standard tier.

Resolution:

Since this is a Unity Catalog enabled workspace, it cannot be reversed and hence it is not possible to downgrade the workspace. you can only migrate the workspace to new or existing standard workspace.

• To migrate data between workspaces, you can use the Databricks Migration Tool, which allows you to migrate objects such as notebooks, cluster configurations, and jobs.
• You can also use tools such as MLflow to copy experiments, runs, and models.
• Additionally, there are scripts available on GitHub that can assist with the migration process.

For more details, refer to Automatic enablement of Unity Catalog and Databricks Migration Tool.
